DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

In one embodiment, a wireless communication system leverages directional communication capabilities to enable environment sensing and mapping. The principles outlined in this disclosure apply to any wireless communication system in which at least one of the transmitter and receiver in the link has directional communication capabilities. The sensing and mapping may be 2D or 3D. The method may provide relative locations of both reflecting surfaces, such as buildings, as well as obstructions that are not reflectors but provide attenuation, such as a tree. One such wireless communication systems is a cellular communications system that includes at least one base station that communicates with a user equipment device. One such system utilizes mmWave 5G cellular communications technology. Beamforming algorithms, for example, are used to efficiently create communication links in cellular communication systems with directional communication capabilities. The advantage of directional communications or mmWave frequencies is used to improve the granularity and resolution of the environment sensing and mapping. Another example is a 60-GHz WLAN communication system. These systems were developed for high-speed (˜1 Gb/s) wireless communication within a room. In this case the result is an indoor environment estimation.

In one embodiment, as shown in FIG. 1, a cellular communication system 100 consists of one or more base stations and one or more user equipment. In the example of FIG. 1, two base stations 12 and 14 and one user equipment 16 are shown. Either or both of the base stations 12 and 14 and the user equipment 16 may include directional communication capabilities. In the example of FIG. 1 the base stations 12 and 14 have the capability to control the direction of multiple beams 18 and 20 and user equipment 16 has the capability to control the direction of multiple beams 22. The directional capabilities may be provided by beamforming, beam-steering, beam-shaping or other directional beam technologies. In the example of FIG. 1, the base station 12 is a mmWave 5G transmitter in an upper floor of a building 24 and the base station 14 is a mmWave 5G transmitter in an upper floor of a building 26. Objects in the environment between the base stations 12, 14 and user equipment 16 include a building 28, tree 30 and truck 32.

In one embodiment of the method of the present disclosure, a first base station 12 sends the beam 18 in a given beam direction to instruct the user equipment 16 to attempt to form a cellular communication a link. The user equipment 16 attempts to make the communication link using beam 22 in the given beam direction. The user equipment 16 extracts and logs a plurality of features for that direction resultant from the link attempt. The features may include communication link metrics such as error vector magnitude (EVM), bit error rate (BER), received signal strength indicator (RSSI), signal-to-noise ratio (SNR), waveform quality factor and signal-to-interference ratio (SIR). For example, a uniform degradation of link quality (as measured by EVM) or uniform attenuation (as measured by a received signal strength indicator RSSI) in several link directions in one polarization may indicate the presence of rain. Other features and metrics resultant from the link attempt, such as the channel frequency response and delay spread, may also be extracted and logged.

The communication link attempts between the first base station 12 and the user equipment 16 are repeated for additional beam directions that the user equipment 16 is capable of forming a beam in. In one embodiment, links may be attempted for all the directions that the user equipment 16 is capable of forming a beam in. The user equipment 16 extracts and logs the plurality of features for the additional beam directions resultant from the link attempts.

In one embodiment, all of the communication link attempts between the first base station 12 and the user equipment 16 for all the directions may be repeated for a different output power from the user equipment 16 and/or a different output power from the first base station 12. The user equipment 16 extracts and logs the plurality of features resultant from the link attempts at the different output power.

In one embodiment, all of the communication link attempts between the first base station 12 and the user equipment 16 for all the directions may be repeated for a different amplitude tapering from the user equipment 16 and/or a different amplitude tapering from the first base station 12. The user equipment 16 extracts and logs the plurality of features resultant from the link attempts at the different output power. Independent phase and gain control may be used at each antenna element for beam forming control.

In one embodiment, all the communication link attempts between the first base station 12 and the user equipment 16 for all the directions may be repeated for one or more additional antenna polarizations. For example, communication links may be attempted in which both the first base station 12 and the user equipment 16 have vertical polarizations, then in which both the first base station 12 and the user equipment 16 have horizontal polarizations and then in which the first base station 12 has a horizontal polarization and the user equipment 16 has a vertical polarization and vise versa. The user equipment 34 extracts and logs the plurality of features resultant from the link attempts at the different polarizations.

In one embodiment, communication links are attempted by the second base station 14 that has access to the same user equipment 16 for a given beam direction of beam 20. In one embodiment, communication link attempts between the second base station 14 and the same user equipment 16 may be repeated for some or all additional directions that the user equipment 16 is capable of forming a beam in. In one embodiment all the communication link attempts between the second base station 14 and the same user equipment 16 for all the directions may be repeated for one or more of different output power and additional antenna polarizations. The user equipment 16 extracts and logs the plurality of features resultant from the link attempts from the second base station 14. In this embodiment, features are collected from a different area of the relevant environmental space. Thus, a rich set of feature information is formed for multiple beam directions, power levels, polarizations and base station locations.

An algorithm converts this set of feature information into inferred 3D environment information such as the presence of walls, buildings and/or foliage. In one embodiment, change in weather conditions may be inferred. Unlike prior art methods based on communication with the detected entities, the present method is capable of extracting information about non-communicating entities in the environment. The inferred environment may include inferred object 34 of the building 28, an inferred object 36 of the tree 30 and an inferred object 38 of truck 32. The method provides relative locations of both reflecting surfaces of the building 38 and the truck 42, as well as obstructions that are not reflectors but provide attenuation such as the tree 40.

FIG. 2 is an example of one embodiment of a system 40 for environment sensing and mapping according to the present disclosure. The system 40 includes a mmWave 5G transmitter (TX) 42 and a mmWave 5G receiver (RX) 44. The TX 42 and RX 44 can both be base-stations, user equipment, or any other device capable of directional communications. A non-communicating entity such as tree 46 is in the environment.

In one embodiment, the system 40 includes a machine learning based intelligent sensing mapping system that leverages directional communication capabilities of the TX 42 and RX 44. Various machine learning algorithms can be used, such a regression, structured and unstructured, supervised and unsupervised, reinforced learning and Bayesian learning.

In an embodiment, the RX 44 in system 40 includes a front end (FE) radio 48 and a computer processing system 50. The computer processing system 50 includes a demodulation and feature extraction module 52 and a machine learning model and inferencing algorithm module 54. The system 40 also includes radio access network (RAN) 56. The FE 48 communicates with the computer processing system 50 and the RAN 56. The TX 42 and RX 44 perform directional communication using one or more beams 58 and 60, respectively. The RX 44 in the FE 48 receives the signals transmitted from the TX 42 and module 52 demodulates and performs feature extraction. Typical receiver demodulation hardware is used to obtain the raw data from the incoming waveforms. Signal processing hardware analyzes the raw data and extracts the features. The features may be in the form of the various communication link metrics. The extracted features may also include Fourier Transform coefficients, coefficients of other mathematical transforms, or other features that may be as a result of the particular environment under consideration. A neural network may also be used for feature extraction. Relevant features can also be extracted prior to demodulation, for example the amplitude of the received signal as estimated by a Received Signal Strength Indicator (RSSI).

The features are locally used by the machine learning model and inferencing algorithm module 54 within the RX 44 to perform 2D or 3D model scoring to create a 2D or 3D inference map. In one embodiment, the raw waveform is fed to the machine learning model and inferencing algorithm 54 in the RX 44 and the machine learning model and inferencing algorithm module 54 extracts the features.

The demodulated data, the extracted features and the 2D or 3D inferences are passed to the RAN 56. The RAN 56 uses the inferences to generate control signals for the TX 42 based on the 2D or 3D environment model. In one embodiment, the RAN 56 uses the inference information from the machine learning model and inferencing algorithm module 54 to perform application specific thresholding for generating of control signals.

In one embodiment, the RAN 56 has the memory and computational resources to include a machine learning model and inference algorithm module 62. The module 62 in one embodiment performs active learning. The RAN 56 expends the machine learning resources and temporary appropriation of TX 42 resources to modify the beamforming based on initial scores from the FE 88 machine learning model 54. Modifications may include more fine grained beamforming or scanning at a higher frequency. The module 62 may use sequence learning using temporal information extracted at the RAN 56 for higher level inferencing that leads to more detailed environment sensing. In one embodiment, the RAN 56 also uses the obtained information to improve its own machine learning model 62. In one embodiment, the RAN 56 periodically updates the machine learning model 54 on the FE 48. In another embodiment, the computer processing system 50 in the RX 44 does not have computing resources to perform feature extraction and inferencing tasks. In this case the demodulated data is communicated directly to the RAN where feature extraction and learning-based algorithm can be executed.

As indicated above, one type of feature that may be extracted from an attempted cellular communication link from a base station to a user equipment device are communication link metrics. One such communication link metric that may be extracted is error vector magnitude (EVM). For example, FIG. 3A shows an EVM data graphic 70 for a transmitter in a building having an equivalent isotropically radiated power (EIRP) of 14 dBm transmitting in a line of site path to a receiver sixty meters away that can be extracted by the demodulation and feature extraction module 52. Links formed when the main lobe is pointed at the transmitter, or any of the four side lobes are pointed at the transmitter 72 are visible in the data. In another example, for a one element transmitter having an EIRP of 10 dBm transmitting to a sixteen element receiver through a large tree may result in the error vector magnitude EVM data graphic 74 shown in FIG. 3B. The data result provides some sense of the environment, possibly including the kind of tree as shown at 76. By increasing the power by using a two element transmitter at 16 dBm EIRP transmitting to the same sixteen element receiver through the large tree may result in the error vector magnitude EVM data graphic 78 shown in FIG. 3C. Three lobes 80 can be seen and more details of the tree can be inferred at 82. This EVM data can be used by the ML model and inferencing algorithm 54 to generate a 2D or 3D environment map.

Various beamforming algorithms can be used that will result in the rich set of features extracted from the communications link attempts. In one example of a beamforming algorithm, that can be used as a tree search algorithm, includes a first stage of initialization that maintains a coarse sector codebook and a fine beam codebook at the transmitter, maintains a coarse sector codebook and a fine beam codebook at the receiver, transmits the transmitter-side codebook information to the receiver and the receiver feeds back the receiver-side codebook information to the transmitter. A second stage of coarse sector training includes for each possible pair of transmit sector i and receive sector j, transmit a training sequence with sector i and receive with sector j, and record the SNR as ½ (i; j). The receiver selects the best pair of transmit sector i

and receive sector j

such that the corresponding SNR is the largest and the receiver feedbacks the transmitter-side sector index i

. A third stage of fine beam training includes for each possible pair of transmit beam p within the coverage of sector i

and receive beam q within the coverage of sector j

, transmit a training sequence with beam p and receive with beam q, and record the SNR as ½(i

; j

; p; q). The receiver selects the best pair of transmit beam p

and receive beam q

such that the corresponding SNR is the largest and the receiver feedbacks the transmitter-side beam index p

. The transmit beam p

and receive beam q

are to be used for data transmissions.

Other beamforming algorithms may be used in the present disclosure. One such further example is the Agile Link algorithm which includes creating a multi-armed beam in different orthogonal directions using subarrays, overlapping directions among different multi-armed beams provides information about the direction of arrival and estimate the direction of arrival using soft-voting to eliminate side-lobe effects. The system can pick multi-armed beams to create random hash functions and estimate the true direction using voting. Another example algorithm is a gradient descent based algorithm.

In one embodiment, the method of the present disclosure may be employed for micro-weather mapping. Mm-Wave channels are heavily dependent on weather. The amount and type of precipitation can be detected using differential attenuation measurements, such as live attenuation compared to attenuation during clear weather. Measurements are real-time and highly localized.

In one embodiment, the method may be employed for air pollution mapping. Mm-Wave channels may be dependent on air pollutants. Air quality can be detected using differential attenuation measurements, such as live attenuation compared to attenuation during clear low pollutant weather. Measurements are real-time and highly localized.
